SPECIFICATION forming part of Letters Patent No. 634,689, Vdated. October 10, 1899.

Application filed September 41 1898l To all whom, it 'may concern? Y Beit known that We, EDWARD M. LAMB and EMMOR BALES, citizens of the United States, residing at Adrian, county of Lenawee, State of Michigan, have invented a certain new and useful Improvement in Machines for Making Toothpicks; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. Y

This invention relates to machines for inaking toothpicks, and has for its object a cutting-olf device to be used in connection with the machine shown and described in Letters Patent No. 588,645, issued August 24, i897.v

In the machine shown in the patent referred to a strand or splint of Wood is driven for-v ward and subjected to cutters which Iturn or rounded-"the strand of wood in a nodular form-that is, that portion of the strand intended for a single toothpick is cut large or swelling at its middle part and is reduced almost to a point at each end. When this strip leaves the cutting-knives, the consecutive parts that are finally to be separated inteindividual toothpicks are joined by a small string or strip of wood that is yet to be cut through when the several picks are separated in the iin al operation of manufacture. In the machine shown in the patent referred to the iinal severing was caused by driving the strip of wood between pins that projected :from a fixed part of the frame and between pins that projected from a vibrating part of the machine, and at the proper momentl the vibrating part of the machine was-reciprocated and the strip of wood severed by breaking the connecting-thread of wood. Practically it. wasfound that the pieces did not break to uniform length, and, moreover,the ends of the l pieces were more or less frayed and bent.

The object of this invention is to produce spoken of in place of the bars with the pins referred to, and this device cuts the picks accurately as to length with aclean cut, so that the ends are unfrayed and unbroken.

In the drawings, Figure 1 is an elevation of the rear end of the toothpick-machine, show- Srial No. 689,996. ilo model.)

mutilated miter gearwheel b,that intermeshes with a bevel gear wheel a, j ournaled in a hanger o'. On the face of the bevel-wheelctis a crank-pin o2, that engages in a slotted link or reach-rod b', The link b is pinned to one end of the lever o, the other end of which engages with a reciprocating knife-bar C, held to a fixed bar D.y The reciprocating knife-bar C is held to the fixed bar D by means of bolts d, that pass through the iiXed bar and through slots d in the reciprocating bar; Through the xed bar, opposite each set of trimming-knives of the machine,`is a conical hole e, faced on its rear side with steel, so that the periphery of the rear edge may be kept sharp. Yrlhrough the reciprocating bar C are other conical holes arranged in pairs, therebein g two such holes for each hole throughthe liked bar D,and the holes of each pair are so spaced that one of them,

c', registers with the hole e when the lever c is thrown over in one direction, apd the other hole, e2, registers with the hole e when the lever c is thrown over in the other direction.

The intermitting motion of the reciprocating hair which is necessary to permit the splint of wood to feed through a. definite distance before it is cut ed, is produced by meansof the mutilated gear-Wheel b, that meshes with the crank-wheel o.. On the mutilated gear-wheel there are half as many teeth as there are on the crank-wheel, and a complete revolution of the mutilated wheel produces a half-revolutionof the crank-wheel, and inasmuch as the mutilated wheel is considerably larger in displint of wood at the proper time and in proper lengths.

IOO

Otherparts ol' the machine do not di lter t'roin the machine described in the patent referred to and form no part of this invention and need not be described.

l. In a machine for making toothpieks, in combination with a fixed cutter-bar, and a reciprocating cutter-bar, a geared crank-wheel and link connection between the crank-wheel and the cutter-bar, and a mutilated gearwheel arranged to mesh with the geared Ve rankwheel, whereby cont-in nous rotary movement of the mutilated wheel produces an intermitting reciprocatory movement of the cutter-bar.

2. In a machine for manufacturingtoothpieks the combination of a xed bar provided with a single perforation for each strand of material operated upon by the machine, a reciprocating cutter-bar provided with two perforations for each strand operated upon and f tion in the presence of two Witnesses.
